Are bone islands hot on bone scan?
Bone islands typically do not appear “hot” on bone scans. The mechanism of increased scintigraphic activity is unclear but has been hypothesized to be related either to increased metabolic activity or to osteoblastic bone remodeling associated with the growth of bone islands.
Should I worry about a bone island?
Bone islands are inert on bone scans, except when they are large. They may be quite active and hence may be worrisome for a malignancy.

How long does a nuclear scan take?
A nuclear scan usually takes about 30 to 60 minutes, plus the waiting time after the radioactive material is given. For bone scans, the material takes 2 to 3 hours to be absorbed.
Does bone island grow?
In 6 cases, unequivocal evidence of growth of bone islands was detected. The intervals over which expansion in size and density occurred varied from two to fourteen years. In one case, which is presented, the pathologic diagnosis of the true nature of the bone island was also available.
How do you treat bone Islands?
Treatment is usually surgery to do a bone graft or add a sclerotherapy medication. Fibrous dysplasia: This is a common bone tumor that shows up as a single bone tumor or multiple bone tumors. Generally, it doesn’t need surgery unless the bone becomes weakened by the size of the tumor.
Can I eat or drink before a bone scan?
EAT/DRINK: Generally, no prior preparation, such as fasting or sedation, is required prior to a bone scan. ALLERGIES: Notify the radiologist or technologist if you are allergic to or sensitive to medications, contrast dyes or iodine. The injection of the radiotracer may cause some slight discomfort.
